Female Latvian opposed to dabblers (10)
I believe the answer is:
dilettanti
'dabblers' is the definition.
(I've seen this before)
'female latvian opposed' is the wordplay.
'female' becomes 'di' (short for Diana).
'latvian' becomes 'Lett' (I've seen this in another clue).
'opposed' becomes 'anti' (similar in meaning).
'di'+'lett'+'anti'='DILETTANTI'
'to' acts as a link.
(Other definitions for dilettanti that I've seen before include "Superficial dabblers" , "those who dabble" , "amateurs" , "art lovers" .)
